托管显示空屏幕时，codeigniter无法正常工作

Question

我开发了一个应用程序并托管它，除弹出框外，一切正常。我正在弹出框中检索一个页面，它在localhost中正常工作但在托管时显示空白页面。这就是我的网址的样子

http://example.com/index.php/employees/view/-1/width:650/random:1409812367964

这是我的index.php

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
    case 'development':
    error_reporting(E_ALL);
    ini_set('display_errors','On'); // <----- added
    break;

    case 'testing':
    case 'production':
    error_reporting(0);
    ini_set('display_errors','Off'); // <----- added
    break;

    default:
    exit('The application environment is not set correctly.');
    }
}
$system_path = 'system'; 
$application_folder = 'application';
if (defined('STDIN'))
{
    chdir(dirname(__FILE__));
}


if (realpath($system_path) !== FALSE)
{
    $system_path = realpath($system_path).'/';
}

// ensure there's a trailing slash
$system_path = rtrim($system_path, '/').'/';

// Is the system path correct?
if ( ! is_dir($system_path))
{
    exit("Your system folder path does not appear to be set correctly. Please open the    following file and correct this: ".pathinfo(__FILE__, PATHINFO_BASENAME));
}

这是我的.htaccess文件
